The teotihuacan civilization

a. flourished on the coast of gulf of mexico
b. was destroyed by the spanish conquistadors
c. never expanded more than a few miles beyond the borders of the city
d. built the pyramid of the sun

The correct answer is the last one:
d. built the Pyramid of the Sun

It was not on the coast, but it was in the center of Mexico - first answer is false.
Also, it was destroyed long before the Spanish conquistadors - it was the Aztecs that were destroyed by the Spanish.

The third option is also false- it had an influence on a big area.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
